Is a 97% battery health decrease within five months normal for MacBook Air?

I wanted to ask if it is normal for the battery health of my Apple MacBook to decrease to 97% within five months of use.


Thank you.

Here is some of Apple's guidance regarding battery health and management:

About battery health management in Mac laptops - Apple Support 



In a nutshell, to get the most from your battery:

• Let the OS and charging circuits manage the charging.

• Plug in when using the computer near available power.

• Use on battery when ac is unavailable or when you must be mobile.

• Don’t subject the computer and battery to extreme temperatures.

• Don’t allow the battery to regularly discharge deeply before plugging in. Yes, it may happen from time to time, just don't make it a habit.

• Don’t obsess over battery life and/or health.
